Effect of creep area with heat source on pre-weaning mortality and weaning body weight of piglets
Introduction:
Mortality of piglets before they weaned accounts to a great loss to the farmers. Around 25% of the piglet’s never attained weaning age and die due to several reasons. This issue is very important in Kohima district where the temperature falls steeply during winter resulting high rate of piglet’s mortality. This can be better achieved by providing a separate creep area, where the piglets have access to heat source while staying within the vicinity of the mother. In this way pre-weaning mortality can be significantly reduces due to cold stress.
Technology Option:
TO1: Creep area with heat source (100 watt bulb)
TO2: Farmers practice: i.e no creep area with heat source & mineral supplementation.

Outcome:
Pre- weaning mortality was recorded nil under technology against farmer’s practice (23.33%) during the study period. Besides, uniform and better litter size at weaning and better health was observed in the technology group as compared to farmers practice. The farmer was able to earn a net return of Rs.30, 150.00 by selling piglet @ Rs.3500.00 per piglet. The benefits cost ratio of technology and farmers practice were recorded 6.1 and 4.5 respectively.
Feedback from the farmers: Farmers were satisfied with the technology as they can observe better litter size & litter body weight at weaning as compared to farmers practice.
Popularization of Vanaraja bird under backyard system
Introduction: Most of the rural backyard poultry production comprises of rearing indigeneous bird with poor production performances. However, the rural backyard poultry production can be easily boost up with improved varieties of poultry bird like Vanaraja, Srinidhi etc that can promise a better production of egg and meat when raised in backyard with low input system. Considering the fact, Krishi Vigyan Kendra Kohima conducted Frontline Demonstration on popularization of Vanaraja bird under backyard system.
Technology: Vanaraja bird
Farmers Practice: Desi / Indigeneous birds.

Outcome:
About 96-97 per cent birds survived during the period of 24 weeks of rearing and attained average body weights of 2.30 kg at 12 weeks of age against the local birds which obtained only 0.603kg. The farmer sold 44.85 kg live body weights at the rate of Rs.350.00 per kilogram in local market and neighbouring villages. The net income earned from sale of birds live weights for Vanaraja and indigeneou birds were Rs. 10,030.00 and Rs.1, 414.00 respectively.
